A country without a national power grid would be horrible and people will die!
It would? They will?
This will be true at first and then people will discover hacks and get on with their lives.
A methane pit can be capped, the methane created once pressurized to become CNC can power an automobile, electric generator, home heating, stoves and so on.
Have you ever figured out how many hours a year do you work just to pay "the corporation" to provide those services? Maybe $5,000 for gas, 7,000 to the electric company. Whatever it is, zero would be better.
If a poop pit isn't your style, solar and wind generators may be an easy to power the simple everyday light bulb but will require space and larger investments for the standard of living we are used to today.
If the national grid went down today, people will limp by for a couple years, develop better methods until some guy promises to rebuild the nation power grid and we'll run him out of town.
Energy in the hands of the few equals control of the many.
